    I had 25 challenging integrals for homework, I got 20 of them done, but the rest I'm either too lazy to continuously try different methods, or I just dont know how to do them. I searched online for the methods to do most of these but nothing came up. Anyways, if you know how to do them, or just LOVE math, wanna show me all the steps? Like type up the u-subs or uv integration by parts or w/e.

    You can check answers here http://integrals.wolfram.com/index.jsp

    anyways here we go, integrate the following (dont know how to do the curvy F on a forum ;P)

    1) x^5sqrt(X^3+1)dx


    2) x7^xdx


    3) sinx/(1-sinx^2)dx


    4) x/((x+2)^1/4)dx


    5)(1+cosx^2)/cosx^2dx



    thanks, and have fun doing maath ;D

    uh dude you only do the quotient rule and product rule on an attempt to find a derivative as far as i know. I think you made a mistake in writing down question 1 and 2, the rest is just basically doing it by logs =x

    thats derivatives, this is integrals or anti derivatives. There's no mistakes in the questions x.x. The x7^x has logs in its answers, and I have no clue how the hell that works ;o.
